This joint cooperative research will study selected steel and concrete buildings in Mexico City which had low seismic resistance as determined from seismic design provisions. Subsequently, these were strengthened through addition of bracing elements or infill walls, and they experienced damage or no damage during severe earthquake ground motion. Laboratory experiments of innovative techniques using concrete-filled steel bracing systems and infill walls will be performed to provide appropriate analytical modelling data and performance data for utilization in remedial strengthening recommendations.

这项联合合作研究将研究墨西哥城选定的钢和混凝土建筑，根据抗震设计规定，这些建筑的抗震能力较低。 随后，通过添加支撑元件或填充墙对它们进行了加固，并且它们在严重的地震地面运动中经历了损坏或没有损坏。 将使用钢混凝土支撑系统和填充墙进行创新技术的实验室实验，以提供适当的分析模型数据和性能数据，用于补救加固建议。
